I have connected Barcode Scanner through USB and i want to read data in VB 6. Prior to this project i have worked on magnetic card reader which i connected through Serial Port and i used MSComm component for that.
Help required please.
Best regards,

It depends on the device driver you are using for the USB scanner. In most cases it will either set up an USB-to-serial COM port or a direct keyboard emulation. Try to check that on the scanner's documentation.

(always loved that one hehe!)

But i dont have manual. i want to know that if MSComm is for serial port then what is the control which can be use with USB port
|
|
|
|

Without the manual, you're pretty much screwed. Yes, MSComm can be used for serial communication. But, does the scanner expose itself as a virtaul COM port?? Probably not. It's probably going to be a keyboard "wedge". In which case, MSComm won't do you any good. You absolutely NEED the manual. Contact the manufacturer or go to their website and see if you can download a copy.

Will i need a USB to Serial Port converter or there is some thing which can be converted to scanner configuration.
|
|
|
|
|
Probably not, and this is precisely why you need the manual.

See what Dave told you.

Vuyiswa Maseko,
Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

Go to your setup project and Right click -->View--> FileSystem-->And in your application Directory right click and -->Add-->File and go and locate MSChrt20.OCX and after that you can compile.
Hope this Helps

Make sure that in the Systems that are not working , go to Solution explorer and make sure that the problem project have reference of that ocx file.

This means that the OCX requires other file(s) to operate that are not included in your deployment. Some of the old MS OCX file assume you have the entire office suit installed on every client and therefore do not encapsulate all their functionality inside themselves.
There used to be a tool called dependency walker[^] that was useful in identifying additional resources for deployment. I have not needed this in years so I have no opinion on its relevance.

Your project requires the MSCHART.ocx and MSCHRT20.ocx because you uses these conponent in your project.
And at the time of setup building these files are not found.
If you can think then I Can.
|
|
|
|
|
I was added Mschart.ocx and MSchrt20.ocx.
and I tried Mschart.dll and MSchrt20.dll (using converter).
But still error is coming.
|
|
|
|
|
You should register those assembly or dll.
If you can think then I Can.
|
|
|
|
|
I done using regsvr32 MSchrt20.ocx
Any other ways to register?

If you have the grid bound to a datasource, it's just a matter of going through the rows in the table that you boud the grid to and adding up those values.

How to close a parent form before loading a child form
thanks
|
|
|
|
|
You can't if you close the parent form the child form will close as well.
|
|
|
|
|
Unless you change the "Shutdown Mode" in the project's properties
If everything was not true, would it be not true that everything is not true? So by saying everything is not true, you are automatically denying that everything is not true. Im so confused...
